Charge management system

Abstract

A charge management system for a battery mounted on an electric vehicle includes processing circuitry configured to: acquire charge-related information that is information on whether charge is possible; acquire power consumption history of the battery; predict a future SOC of the battery based on the power consumption history; set a scheduled charge date when a predicted SOC value of the battery is predicted to decrease to a threshold or less; and notify the scheduled charge date. The processing circuitry sets the scheduled charge date based on the charge-related information.

What is claimed is: 
     
         1 . A charge management system for a battery mounted on an electric vehicle, the charge management system comprising
 processing circuitry configured to:
 acquire charge-related information that is information on whether charge is possible; 
 acquire power consumption history of the battery; 
 predict a future SOC of the battery based on the power consumption history; 
 set a scheduled charge date when a predicted SOC value of the battery is predicted to decrease to a threshold or less; and 
 notify the scheduled charge date, 
   wherein the processing circuitry sets the scheduled charge date based on the charge-related information.   
     
     
         2 . The charge management system according to  claim 1 ,
 wherein the charge-related information includes information on a schedule of a user, and   wherein the processing circuitry sets the scheduled charge date based on the schedule of the user.   
     
     
         3 . The charge management system according to  claim 1 ,
 wherein the charge-related information includes information on a reservation status of charge equipment, and   wherein the processing circuitry sets the scheduled charge date based on the reservation status of the charge equipment.   
     
     
         4 . The charge management system according to  claim 3 ,
 wherein the processing circuitry is further configured to reserve the charge equipment before notifying the user of the scheduled charge date.   
     
     
         5 . The charge management system according to  claim 1 ,
 wherein the charge-related information includes weather information of a charge site, and   wherein the processing circuitry sets the scheduled charge date based on the weather information.   
     
     
         6 . The charge management system according to  claim 1 ,
 wherein the processing circuitry selects a plurality of candidate dates earlier than an expected date on which a predicted SOC value of the battery decreases to a threshold or less, and sets the scheduled charge date from the plurality of candidate dates.
